TRANSOM REGULATING AND SECURING MECHANISM.

Specification of Letters Patent.

Patented April 7, 1908.

Application filed February 21, 1907. Serial N 0. 358,705.

To all whom it may concern:

Beit known that I, HENRY BRADLEY, a citizen of the United States, residing at Caney, in the county of Montgomery and State of Kansas, have invented certain new and useful Improvements in Transom Regulating and Securing Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in attachments for doors and means to regulate the same and my object is to provide a door with an opening in the upper portion thereof and secure therein a transom in the form of a hinged panel or ventilator.

A further object is to provide means for automatically raising the ventilator when the same has been released.

A further object is to provide means for holding the ventilator at various angles and a still further object is to provide means for securely locking the hinged panel in its closed position.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawing which is made a part of this application the figure shows a perspective view of a door having my improved hingedpanel or ventilator secured in an opening therein together with means for operating the ventilator.

Referring to the drawings in which similar reference numerals designate corresponding parts, 1 indicates a door which may be of the usual or any preferred form in the upper end of which is formed an opening 2 in which is disposed the usual or any preferred form of hinged panel or ventilator 3, said hinged panel being secured in the opening by means of hinges 4, said hinges being at the upper edge of the hinged panel so that the hinged panel may be swung upwardly when it is desired to ventilate the room while the lower edge of the hinged panel is provided with a housing in which is mounted a spring operated latch 5 which is adapted to engage a keeper 6 secured to the face of the door and adjacent the lower edge of the opening 2 so that when the hinged panel is completely lowered or closed, the latch 5 will engage the l keeper and hold the hinged panel in its closed position.

In order to automatically raise the hinged panel when the latch 5 is disengaged from the keeper 6 I secure to the upper end of the door one end ofa tension spring 7 while the opposite end thereof is secured to an arm 8 w ch is in turn secured to the housing for the latch 5 so that when said latch is disengaged from the keeper, the s ring will exert tension upon the hinged pane and swing the same upwardly on its hinges 4.

Owing to the varied temperature of the weather it is desirable to have the ventilator so arranged as to open wider at one time than another and in order to regulate the movement of the hinged panel and thereby increase or decrease the ventilation I secure to the door 1 adjacent one end of the hinged panel, a frame 9 on which is rotatably mounted a head 10 in the lower face of which is seated a cam slot 11 with which engages a stem 12 which is in turn secured to a bar 13, said bar having at its outer free end a plate 14 which is adapted to engage the end of the hinged panel 3 to hold the same in its adjusted position when the head is rotated a certain distance in one direction.

The rotation of the head 10 is employed to direct the plate into or out of engagement with the hinged panel after the same has been opened the desired distance and the cam slot 11 is so arranged that the plate 14 may be extended slightly beyond the end of the hinged panel 3 when the head is rotated to its fullest stroke so that when the hinged panel is closed the plate may be directed over the face of the hinged panel and the bar 13 employed for lockingthe hinged panel in its closed position so that it will be impossible to open the hinged panel from the opposite side of the door.

While I have shown the hinged panel as secured to an opening in a door, it will be readily understood that said hinged panel maybe located in the usual manner above the door or at any desired point in a frame, etc.

It will now be seen that I have provided a very cheap and economical means for forming a ventilator in the upper portion of a door and provided devices for raising and locking the ventilator in its adjusted position and also for locking the same in its closed position and further that the locking mechanism can be attached to any form of hinged panel which is hung in the manner described and adapted to swing upwardly.

What I claim is:

1. The combination With a door and a hinged panel hinged at its upper edge, of a spring actuated latch on the panel, a keeper on the door, an arm on the housing of the latch, a spring in alinement with said latch and having one end secured to said arm and the other end to a relatively fixed part and arranged to exert tension on the panel to swing the same upward on its hinges, and means on the door engageable with the end of said panel and constructed to regulate the movement of said panel and having provision for engaging and locking said panel in its closed position.

-2. The combination with a door and a hinged panel hinged at its upper edge and a latch therefor, of an arm attached to said panel, a spring in alinement with said latch and attac ed at one end to said arm and at its other end to said door to raise the panel when the latch is disengaged, and means fixed relatively to said anel and carrying a plate engageable with t e end of the panel to hold the latter in its adjusted position and movable over the face of the panel to lock it in its closed position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HENRY BRADLEY.
